How To Choose An Indoor LED Company That Is Reliable And Cost-effective

I have been working in the LED display industry for more than ten years, and I have seen too many customers make mistakes when choosing indoor LED companies. Some people only focus on the price, but it breaks down in just three months after installation; some people blindly pursue big brands, and their budgets are doubled. Today I will tell you everything about this industry.

Indoor LED displays have been widely used in conference rooms, exhibition halls, shopping malls, hotels and other places. A good screen can instantly improve the quality of a space. A poor screen is not only ugly, but also often malfunctions, affecting normal operations. Choosing the right company is really important.

How to choose a reliable indoor LED company

When choosing an LED company for home use, you can't just listen to the sales staff here's hype, you have to actually see how much hard power they have. Really reliable companies generally have their own independent research and development teams, and are not the kind of pure trading traders who just take other people's ready-made modules and sell them directly. You can ask the other party if they have their own independent production line, where is the specific location of their production factory, and how big and small is it?

It is also extremely important to observe cases: ask the other party to provide similar types of projects that have been undertaken in the past six months. It is best to conduct on-site inspections, or ask the other party to take images to convey to you. Only through on-site inspection can you clearly identify the screen installation effect, color uniformity, and whether there are bad pixels. Some companies appear to be regular and formal on the surface, but in fact the core components are imported from outside, and each other shirks responsibility when it comes to the key points. This must be avoided and eliminated.

Many people tend to ignore after-sales service. It is impossible for electronic equipment not to have LED problems such as screens. Reliable manufacturers will promise a warranty. Some provide a three-year warranty, and some even longer. You also need to ask about the response time, how long it takes for someone to repair a similar fault, whether remote guidance can solve it, and whether spare parts are ready and available. These are all service indicators that are assessed.

How much does an indoor LED screen cost per square meter?

The price of indoor LED electronic screens ranges widely, from more than one thousand to tens of thousands, mainly depending on the size of the pixel spacing. The so-called point spacing is the distance value between the center points of two LED light-emitting lamp beads. The smaller the value, the more delicate the picture will be, and of course the higher the corresponding cost will be.

P1.2 to P1.5 are ultra-small pitches, and the image quality is close to that of LCD splicing screens, but the size can be made very large. This type of product is generally used in high-end conference rooms, command centers, exhibition halls and other places, and the price is usually around RMB 6,000 to RMB 50,000 per square meter.

At present, the most widely used indoor range is P1.5 to P2.5, and the cost performance is relatively balanced. The picture clarity is sufficient to meet most relevant needs, and the relevant price is roughly in the range of 3,000 yuan to 8,000 yuan per square meter. For small-pitch LED technology that has been in the rapid development stage in the past two years, in the past few years, only a few large-scale brand companies could achieve the corresponding value of the product below P1.5, but now even many second-tier brands are now able to understand the core technology, and the corresponding prices can become more affordable.

P2.5 and even P4 are conventional spacings, which are suitable for places with longer viewing distances, such as large conference halls, churches, and shopping mall atriums. The market price per square meter ranges from 2,000 yuan to around 4,000 yuan. It is really a standard choice for customers with tight budget space.

P4 and above specifications are generally used in various situations with larger areas and required viewing distances of more than ten meters. The cost is relatively low, but there will be obvious grain resolution problems when viewed closely, and they are not suitable for situations that require very high image quality.

What are the indoor LED display brands?

After more than ten years of development, the domestic LED display industry has created a relatively clear brand echelon. The first-tier brands are represented by Leyard, Unilumin Technology, Absen, and Alto Electronics. These companies have been on the market for many years, and their technical accumulation is profound and difficult to change. Their product performance is extremely stable and reliable, and the corresponding prices are relatively high.

There are a large number of second-tier brands, mainly concentrated in Shenzhen, Dongguan and other places. Some of these companies focus on a certain segment, and some do quite well in terms of cost performance. For customer groups with limited budgets, leading companies in the second-tier brand category are also good choices.

Some customers only recognize foreign brands and think imported ones must be better. In fact, the quality of domestic LED lamp beads and driver ICs is no longer bad. In most indoor application scenarios, the performance of domestic brands can match or even surpass foreign products, but the price is much cheaper.

Choosing a brand also depends on the specific model: different series of products from the same company may have very different positioning and related quality; do not just focus on the brand when choosing, be sure to understand the exact series of the selected product, what kind of lamp bead combination and IC solution it uses.

Which indoor LED screen manufacturer has good quality?

The quality of indoor LED screens lies in several key points. The choice of lamp bead brand is crucial. Common brands such as National Star Optoelectronics, Hongjing Optoelectronics, and Bridgelux are available. Lamp beads of different grades have very obvious differences in terms of brightness consistency, dead light rate control, and attenuation speed.

The driver IC directly affects the display effect. ICs from brands such as Taidao Jingtai and Nationstar are relatively stable in grayscale performance and refresh rate. Some low-price products use off-brand ICs, and the images are prone to flicker, hue and other issues.

The consistency of the cabinet is also very important. Excellent manufacturers will do step-by-step calibration to ensure that the brightness and color of each lamp bead are as similar as possible, so that the entire screen will have no color difference and dark areas. Even if the calibration is excellent, the visual performance will not be much worse even if it is used for several months.

Thermal dissipation design determines the life of the screen. LED lamp beads will generate heat when working. If the thermal conditions are not good, it will cause light attenuation to accelerate and color drift. Excellent cabinet design will have reasonable heat dissipation channels and fans or heat sinks will be installed when necessary.

Indoor LED display installation precautions

The quality of installation directly affects the user experience. The wall must be flat and solid. If it is a suspended installation, the wall load must meet the specified standards. When installing on the ground, attention must be paid to the foundation being firm, to prevent shock and vibration from affecting the screen.

The heat dissipation space cannot be underestimated. Sufficient ventilation space must be left around the screen. It is best to lay a heat dissipation channel behind the screen. If conditions permit, an exhaust fan can be installed to help dissipate heat and cool down during the high temperature period in summer.

The power supply system needs to be independent and reliable. The current impact is extremely large when the LED screen is started. It is recommended to configure a special air switch and voltage regulator. The diameter of the power supply wire must meet the thickness requirements and be careful to prevent voltage drops causing uneven brightness.

Signal transmission lines should be kept away from strong current lines to avoid electromagnetic interference causing screen flickering or stripes. Optical fiber signal forwarding can be used for long-distance transmission, which has better stability.

After debugging is completed, it needs to be run for a period of time to test and detect whether there are any dark areas and color blocks in the dead light. Don't wait for the acceptance to be completed before re-doing it will cause more trouble and costs. If the problem arises, it should be dealt with in a timely manner.
